android设置动画
android设置动画  一个条目点击后先向左滑动，然后向右滑动，最后回到开始的位置，怎么写代码？？？？？？我设置了集合set，但他们是同时进行的，代码如下：
TranslateAnimation ta = new TranslateAnimation(
Animation.RELATIVE_TO_SELF, 0.0f,
Animation.RELATIVE_TO_SELF, -0.3f,
Animation.RELATIVE_TO_SELF, 0.0f,
Animation.RELATIVE_TO_SELF, 0.0f);
ta.setDuration(2000);
view.setAnimation(ta);
TranslateAnimation ta1 = new TranslateAnimation(
Animation.RELATIVE_TO_SELF, 0.0f,
Animation.RELATIVE_TO_SELF, 0.5f,
Animation.RELATIVE_TO_SELF, 0.0f,
Animation.RELATIVE_TO_SELF, 0.0f);
ta.setDuration(2000);
set.addAnimation(ta);
 set.addAnimation(ta1);

view.setAnimation(set);
------解决方案--------------------

	AnimationSet set = new AnimationSet(true);
							TranslateAnimation ta = new TranslateAnimation(
									Animation.RELATIVE_TO_SELF, 0.0f,
									Animation.RELATIVE_TO_SELF, -0.3f,
									Animation.RELATIVE_TO_SELF, 0.0f,
									Animation.RELATIVE_TO_SELF, 0.0f);
							ta.setDuration(2000);
							TranslateAnimation ta1 = new TranslateAnimation(
									Animation.RELATIVE_TO_SELF, 0.0f,
									Animation.RELATIVE_TO_SELF, 0.5f,
									Animation.RELATIVE_TO_SELF, 0.0f,
									Animation.RELATIVE_TO_SELF, 0.0f);
							ta1.setDuration(2000);
							ta1.setStartOffset(2000);
							set.addAnimation(ta);
							set.addAnimation(ta1);
							view.startAnimation(set);
